This is a two part video
that explores the interrelationship of people and a fresh water
ecosystem, and provides guidance for local stream monitoring projects.
Fresh Waters Flowing,
Part One, explores the connection between humans and rivers,
specifically the links between human influence and the ability of a
river to support healthy living communities. Fresh Waters Flowing
shows how important biological integrity is for rivers and demonstrates
how measuring biological condition with the index of biological
integrity (IBI) can be a powerful tool for maintaining and restoring the
health of watersheds.
Biological Monitoring Protocol,
Part Two, introduces the index of biological integrity (IBI) as the best
yardstick for measuring the health of rivers and streams. Measuring
pollutants, such as temperature, phosphorus, or toxic chemicals, may
tell you if a river is clean, but only a direct biological yardstick
like IBI will tell you if a river is healthy and can, for example,
support wild salmon.
IBI has now been adopted to monitor rivers
on all continents except Antarctica. This program also outlines the
actual equipment and techniques needed to collect data as an index of
Featuring James Karr of the University of
Washington and Charley Dewberry of Pacific Rivers Council, this
two-video series introduces important science concepts and is
appropriate for courses in natural science, environmental science,
biology, and water quality at the high school and university levels.
